I have a 15 HP Chrysler outboard motor that I purchased new in 1976. The check valves in the cylinder drain cover are passing air in both directions. These valves are 1/4'' in diameter and 1/4'' long. Being that small they must have been controlled by some sort of flapper or disc.
Does anyone know of any new replacement covers, used ones with working check valves or just replacement check valves?
